PCT AG-IP 10.043 In what cases are these fees refunded?

10.043. In what cases are these fees refunded? The International Preliminary Examining Authority will refund the handling fee if the demand is withdrawn before being sent to the International Bureau or if the demand is considered not to have been submitted because none of the applicants had the right to file a demand (see paragraph 10.004). Each International Preliminary Examining Authority decides at its discretion whether it will refund the preliminary examination fee, or any part thereof, in other circumstances. Details are indicated in Annex E.
